At the recent Newbury show I bought a tuning module that plugs into the end of the common rail on top of the engine from Torquing Diesel.
The module is a plug-in, removable electronic device which generates extra efficiency & boosts economy. It can be removed at any time & does not in any way affect engine management or make any permanent changes to original specification.
When the device is removed, the vehicle reverts entirely to standard operation/performance. It can be fitted by you as it only requires you to unplug the connector on the common rail and plug the unit in the plug the original lead into the module.
It is not a remap & that the equipment is removable. It also comes with a 45 day money back guarantee if your not happy with the performance.
I have contacted my insurer (Caravan Guard) and they have noted it on the policy at no additional cost
I usually get an MPG of approx 22.5 (65 on Satnag, 68 on dash, on cruise), however on arrival at Newbury it was 21.7
The run back home to Portsmouth took about an hour and we got an MPG of 27.1. This was at a slightly slower pace due to the wind but I expect it will save an average of 4-5 mpg. Being a pessimistic sort I expect it will give me a 15% possible 20% improvement in MPG, which at £1.40 a ltr will save 20 to 28p.
With a 90 ltr tank it will reduce the cost of a fill by £20 or so (or give me the extra distance between fills if that makes sense).
So far Im impressed with it but time will tell, were going to Tewksbury next weekend so I will post on the MPG on our return.
The other thing Ive noticed is the better power which has reduced the number of gear changes you have to make when overtaking or in traffic (got to be good for a Fiat Clutch ). I have emailed Mark the owner and asked him to consider a discount for members if anyone wants one. I will post more when I get a response.
I totally disregard the trip computer for reading out MPG, it all depends on how you drive for the first 15-20 miles and from that point doesn't really budge.
I've done 4500 miles in the last 7 weeks away and recorded the MPG tank-to-tank, it is nothing like the trip computer which reads both over and under the actual.
After having both a plug and play box and a remap, I would opt for a remap every time but only on a van out of warranty since a box can easily be removed without involving the tuner.
At the risk of embarassing myself, i can reveal i forked out for a welknown one of these tuning devices some 4 years ago, hence my interest in others findings......
It was fitted to a megane 1.5 diesel 100 hp....
I had always marvelled at the accuracy of the dashboard trip/ mpg dogs danglies thingy and knew the tank held 13 gallon and at an indicated average 50 mpg low and behold i got 650 miles to a tankfull and i needed to fill up....
I was ecstatic to get an average 65 mpg indicated when i fitted the tuning chip and the power increase took the car to 130hp, i dont doubt was there....
Weeks later i filled the car right up and noticed i needed to fill again having only done 500 miles despite the 65 mpg indication and thus expecting well over 700 miles, so i paid a bit more attention to things...
---------
There are 2 types of these devices, one that is active throughout the rev band and one that is more sophisticated and cuts in higher up the rev band or as you floor it up hill ... i chose the unsophisticated one as i prefered the relaxed driving rather than the heavy foot the later induced in the driver as the power was addictive ! ....
----------
I can only conclude my car was using far more fuel and the trip thingy on the dashboard was somehow fooled into indicating a better mpg , the former not suprising considdering i had 30 % more power... I decided to wire a multi contact relay and resided to flick a switch to engage it solely for uphill and overtaking manoevers but the story doesnt end there..
The car is very low mileage , but 2 years ago it developed an injection fault and the injectors were "leaking" causing air bubles in the return fuel system that were then recycled into the injection pump after a visit to the fuel filter and there came a time when it would nt start and 2 of the injectors were replaced....
The fix didnt last long and i had to do some real creative thinking to be able to get the car useable....
Whilst i have no conclusive proof the tuning chip was responsible, i m interested to know what these things do when hooked up and strongly suspect they simply increase the fuel injected in to gain the power and the better mpg is a bit of a mith probably born out of the dashboard average mpg thingy.....
If these devices are so damn clever and good how come the manufacturers dont offer them as an aftermarket add on ????
Its a bit like the magnets that "re-arange" the molecules in the fuel to give better MPG !!! If it worked every single manufacturer would fit them as standard wouldnt they???
Do I seem to be cynical??? Thats because I am. I always remember the old sayings
"The other mans grass is allways greener"
AND
"A fool and his money are soon parted"
Some good comments, just what I wanted. I will fill the van to the brim before going to Tewsbury this weeked and agine when we get back to see how much it actually cost and if the dash computer is reading higher than normally.
The run down from Newbury was only short but the dash computer had stabalised by the time we got home, but only a long run will tell. I will post the results after the weekend
No doubt these devices do something to enhance performance.
Surely with enhanced performance there is an increase in fuel consumption
Dash computers are not as acurate as fill to fill calculations.
From home down to Dover , 250 miles I always use less fuel than in the reverse direction.

Nothing to do with chipping etc but I used my cruise control for a lot of the autoroute sections on my recent France trip.
I noticed that when I had the cruise control set at 60mph it would power up the slopes without loosing speed or changes to the revs in 6th gear. When I drove it with the cruise control off I appear to loose revs and speed on the same slopes and have to change to 5th. It appears my driving techniques is different than the cruise controls one but I was impressed with the performance with the cruise control set.
